+
+Required properties:
+ - compatible: "mediatek,mt8173-vpu"
+ - reg: Must contain an entry for each entry in reg-names.
+ - reg-names: Must include the following entries:
+ "tcm": tcm base
+ "cfg_reg": Main configuration registers base
+ - interrupts: interrupt number to the cpu.
+ - clocks : clock name from clock manager
+ - clock-names: must be main. It is the main clock of VPU
+
+Optional properties:
+ - memory-region: phandle to a node describing memory (see
+ Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt)
+ to be used for VPU extended memory; if not present, VPU may be located

+
+Example:

+Renesas R-Car Frame Compression Processor (FCP)
+-----------------------------------------------
+
+The FCP is a companion module of video processing modules in the Renesas R-Car
+Gen3 SoCs. It provides data compression and decompression, data caching, and
+conversion of AXI transactions in order to reduce the memory bandwidth.
+
+There are three types of FCP: FCP for Codec (FCPC), FCP for VSP (FCPV) and FCP
+for FDP (FCPF). Their configuration and behaviour depend on the module they
+are paired with. These DT bindings currently support the FCPV only.
+
+ - compatible: Must be one or more of the following
+
+ - "renesas,r8a7795-fcpv" for R8A7795 (R-Car H3) compatible 'FCP for VSP'
+ - "renesas,fcpv" for generic compatible 'FCP for VSP'
+
+ When compatible with the generic version, nodes must list the
+ SoC-specific version corresponding to the platform first, followed by the
+ family-specific and/or generic versions.
+
+ - reg: the register base and size for the device registers
+ - clocks: Reference to the functional clock
+
+
+Device node example
+-------------------
+
+ fcpvd1: fcp@fea2f000 {
+ compatible = "renesas,r8a7795-fcpv", "renesas,fcpv";
+ reg = <0 0xfea2f000 0 0x200>;

-Driver general quality is not good enough for mainline. Also, other
-device drivers (USB-bridge, tuner) needed for Astrometa receiver in
-question could need some changes. However, if that driver is mainlined
-due to some other device than Astrometa, unrelated TODOs could be
-skipped. In that case rtl28xxu driver needs module parameter to prevent
-driver loading.
-
-Required TODOs:
-* missing lock flags
-* I2C errors
-* tuner sensitivity
-
-*Do not* send any patch fixing checkpatch.pl issues. Currently it passes
-checkpatch.pl tests. I don't want waste my time to review this kind of
-trivial stuff. *Do not* add missing register I/O error checks. Those are
-missing for the reason it is much easier to compare I2C data sniffs when
-there is less lines. Those error checks are about the last thing to be added.
-
-Patches should be submitted to:
-linux-media@vger.kernel.org and Antti Palosaari <crope@iki.fi>

-This driver is deprecated: it should become a stand-alone driver instead of
-using the soc-camera framework.
-
-Unless someone is willing to take this on (unlikely with such ancient
-hardware) it is going to be removed from the kernel soon.
-
-Note that trivial patches will not be accepted anymore, only a full conversion.
-
-If you want to convert this driver, please contact the linux-media mailinglist
-(see http://linuxtv.org/lists.php).
